In a 43-second YouTube clip,
Quaid is heard screaming at crew members:

What the f---! 'Keep going?' I am acting here, and this d---head
wanders onto my set. I can’t even get a line out until dopey the
d--- starts whispering in your ear and you’re not even watching
anymore ... Don’t f------ Dennis me! I am doing my job here. I am
a pro. This is the most unprofessional set I have ever been on.
This is horses---! I've got these f------- zombies over here that
I have to look at. I have a bunch of p------ staring at me, and
this f------ baby. This is garbage! ... Blow me!

"A number of commenters on Reddit, where the video with over 460,000 views has
been upvoted over 4,000 times, are speculating it’s a prank for
'Jimmy Kimmel Live!' — a late-night show that has had its
fair share of viral hoaxes," notes The Wrap. "One commenter on the site even
said he works for the ABC talk show, and can 'confirm' it’s a
prank."
